Problem using different Map key types in one class

Question

I'm running Kodo 2.3.3. It seems I can only have one Map key types for all
maps in a class. For example, if I have two maps in a class, their keys
must be of the same type.
Is there a plan to remove this limitation soon?
Thanks,

Kodo should generate a separate table for each Map. We have internal tests
that use classes with Map fields using a lot of different key/value type
combinations, so there shouldn\'t be a problem.It looks like two maps (keyValues and versions) are sharing the same
table. Here is the table generated by schematool (db: Oracle 8.1.7):
desc persistentmotiveresourcebean_x;
Name Null? Type
ID_JDOIDX VARCHAR2(255)
JDOKEYX NUMBER
KEYVALUESX VARCHAR2(255)
VERSIONSX VARCHAR2(255)

Following is the simplified code I run:
-----------internal.jdo--------------------------------------
<?xml version=\"1.0\"?>
<jdo>
<package
name=\"com.motive.services.resourceManagementService.internal\">
<class name=\"PersistentMotiveResourceBean\"
identity-type=\"application\"
objectid-class=\"com.motive.model.PrimaryKey\">
<field name=\"id\" primary-key=\"true\"/>
<field name=\"versions\">
<map key-type=\"java.lang.Float\"
embedded-key=\"true\" value-type=\"java.lang.String\"
embedded-value=\"true\"/>
</field>
<field name=\"keyValues\">
<map key-type=\"java.lang.String\"
embedded-key=\"true\" value-type=\"java.lang.String\"
embedded-value=\"true\"/>
</field>
</class>
</package>
</jdo>
Java source:
-----------PersistentMotiveResourceBean.java---------
package com.motive.services.resourceManagementService.internal;
import java.util.HashMap;
public class PersistentMotiveResourceBean
private String id;
private String name;
private HashMap versions;
private HashMap keyValues;
public PersistentMotiveResourceBean()
public String getId() { return id; }
public void setId(String id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public HashMap getVersions() { return versions; }
public void setVersions(HashMap versions) { this.versions = versions; }
public HashMap getKeyValues() { return keyValues; }
public void setKeyValues(HashMap keyValues) { this.keyValues =
keyValues; }
----------------PrimaryKey.java-------------------------------------
package com.motive.model;
import java.io.Serializable;
public class PrimaryKey implements Serializable
public String id;
public PrimaryKey ()
public PrimaryKey (String id)
this.id = id;
public boolean equals (Object ob)
if (this == ob) return true;
if (!(ob instanceof PrimaryKey)) return false;
PrimaryKey o = (PrimaryKey) ob;
return (this.id == o.id);
